Description

Technical Field

[0001] The present invention belongs to the field of functional coatings and energy utilization, and specifically relates to a protein-based photothermal super-hydrophobic coating and a preparation method and application thereof. Background Art

[0002] Superhydrophobic coatings have shown important application value in the fields of anti-corrosion, anti-fouling, and anti-icing due to their unique water repellency and self-cleaning ability. Traditional superhydrophobic coatings mostly rely on fluorine-containing compounds (such as perfluoroalkyl substances) or inorganic nanoparticles (such as silica) to construct micro-nano rough structures, but these materials have problems such as environmental toxicity, poor biodegradability, and complex preparation processes. In addition, the existing superhydrophobic coatings have a single function and are difficult to meet the needs of multiple scenarios in complex environments (such as solar-driven deicing, photothermal sterilization, etc.). In recent years, the combination of photothermal materials (such as precious metal nanoparticles, carbon-based materials) and superhydrophobic coatings has become a research hotspot. By introducing light-absorbing materials into the coating system, local warming can be achieved under light, thereby enhancing anti-icing, self-cleaning or antibacterial properties. However, existing photothermal superhydrophobic coatings still face the following challenges: (1) Insufficient environmental friendliness: Photothermal components such as precious metals (gold, silver) or carbon nanotubes are expensive and may release harmful nanoparticles; (2) Limited biocompatibility: Synthetic materials are difficult to adapt to medical or food contact scenarios; (3) Poor functional synergy: The integration of photothermal effect and superhydrophobic properties often leads to decreased structural stability. For example, high temperature may destroy the micro-nano rough structure.

[0003] At the same time, bio-based materials have attracted much attention due to their renewability and environmental friendliness. Proteins (such as silk fibroin and zein) as natural polymers have excellent film-forming properties, degradability and chemical modification potential, and have been attempted to be used in the development of green coatings. However, pure protein-based coatings often have defects such as low mechanical strength, insufficient hydrophobicity (contact angle is usually less than 120°) and single function. In the existing technology, although some studies have improved the hydrophobicity of protein coatings by doping hydrophobic particles (such as silica) or chemical modification, such methods may sacrifice their biocompatibility and fail to give the coatings multifunctional properties such as photothermal properties.

[0004] In summary, there is still a significant gap in developing a coating technology that is environmentally friendly, highly hydrophobic, has a stable photothermal effect, and is adaptable to multiple scenarios. Summary of the Invention

[0005] The purpose of the present invention is to provide a protein-based photothermal superhydrophobic coating with excellent superhydrophobicity, good photoinduced warming property and cyclic stability and a preparation method thereof.
